l[o all whom, it may concern,.-

Be it known that I, HENRY ALBERT, a citi- Zen of the United States, residing at Crescent City, county of Del Norte, State of California, have invented an Improvement in CanLabeling Machines; and I hereby declare the following tobe a full, clear, and exact description of the same.

My invention relates to a can-labeling machine.

It consists in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a side elevation of the machine. Fig. 2 is a longitudinal vertical section of the lower part of the machine enlarged. Fig. 3 is a plan View of the.l mechanism for actuating the locks and label-holders. Fig. -l is a vertical transverse section of the same. Fig. 5 is a vertical transverse section taken through .fr of Fig. 2. Fig. 6 is an enlarged transverse view of the paste holder, showing rollers, platen, and attachments. Fig. 7 is a top view ofthe fat-edge scrapervW; Fig. 8 shows a means for making the paste-edge stems adjustable. Fig. 9 is a sectional View through the runway on the line 2 2 of Fig. 1. Figs. 10 and 1l are details showing the holders for the paste-heads T.

The object of myinvention is to provide an apparatus into which cans to be labeled are delivered; a means for placing said cans within a can-puller, which moves them over the chamber containing the labels to be applied; a means for applying paste to the ends of said labels, pressing the can down, so that the label will be applied and rolled upon it as it passes above the label-chamber, and in certain details of construction.

This invention is an improvement upon an apparatus for which Letters Patent were issued to me October 6, 1891, No. 460,738.

The apparatus consists of a runway, into one end ot' which the cans are delivered from an inclined chute in which they travel; a table upon which the cans are received singly from the chute; a means for elevatingthe table and can, so that the latter is delivered into the can-puller; a mechanism -by which the canpuller is advanced along the runway, moving the can with it; a paste-receptacle at the opposite end of the runway, with rollers by which the paste is delivered and distributed upon the under side of a horizontally-moving platen, from which the paste is distributed upon a roller carried by the can-puller, the paste being in turn delivered from this roller to vertically-reciprocating paste-heads, by which it is applied successively to the ends of the uppermost of the labels containedin the chamber, in which they are fed upwardly into the line of travel of the rolling cans, so that the cans will pick the labels up, roll them upon the cans, and apply them smoothly thereon, after which the cans are discharge at the end of the machine.

The can-puller D is adapted to reciprocate within the runway a. It is mounted in the runway by means of outwardly-extending slide-pins CZ or` dat plates, if preferred, and these move freely in horizontal slots or tracks a made in thesides of the runway. These slide pins or pieces extend outside of the slots in the runway andpass through verticallyslotted carriers which lit upon the outside of .the runway andare secured to the screwthreaded ends of the pins by nuts, so that the can-puller and these carriers are connected and move together, the former on theinside and the latter on the outside of the runway.

The movement of the vcan-puller s effected by the following mechanism: A driving-shaft B has on one or both ends suitable driving mechanism and a central crank b, which is rotated when the shaft is turned. This shaft is supported upon standards near one end of the machine. In the present case it is shown above the paste-box. Near the other end of the machine are standards F, in the upperend of which a shaft f is journaled. From this shaft arms E extend` downward just outside of the carriers D and have pins projecting in-Y wardly into the vertical gutters or channels d2 in these carriers. The arms E are connected with the crank b by a connecting rod or yoke b', and as the crank revolves thearms IOO llO

vjustable supports c.

provided with antifriction-rollers to move up and down in the channels as the arms oscillate abouttheir fulcru m-shaft at the top.

E are corresponding swinging arms fulcrumed upon a shaft f', which is journaled parallel with the shaft f and a short distance therefrom, as shown in Fig. l, and the lower ends of the arms E are connected with the arms E by a connecting-rod e, so that these arms partake of the same swinging movement with the arms E when the crank revolves. The vertically-moving paste-heads are actuated by mechanism operated by these swinging arms, as will be hereinafter described.

The receptacle C for the paste consists of a suitable vessel of any material mounted near the discharge end of the machine upon adflhe legs of these supports pass through the main frame and are provided with adjusting-nuts c', so that the paste-receptacle may be raised and lowered with reference to the paste-roller upon the can-puller, so that the latter may pass under the sliding` platen of the paste-box and make the proper contact therewith. The box itself has short legs c2, which enter holes in the support upon which it rests, and these allow the box to be taken off at any time for cleaning and returnedto its place without the necessity of any further adjustment. The box can b'e made fast in its place by set-screws or other suitable locking mechanism. Within the box are journaled two transverse rollers c5 c4. These rollers are supported in guides c6, which allow them to'be easily removedand replaced, and they are retained in perfect contact with each other. The upper roller vc3 is formed with grooves or channels, and in the present case the lower roller is shown as being made plain. Each or both may be composed of or covered with rubber or-other substance which will ladapt them to readily take up the paste, and the grooves in the upper roller enable it to carry a suflicient amount and to transfer it readily to the sliding platen c5, which travels horizontally in guides on the top of the box. This sliding platen is moved forward and backward above the box and receives the paste from' the upper roller when it moves over this roller and delivers it, as will be hereinafter described, to a roller upon the can-puller. The feedrollers are held up by a small spring c7, mounted in blocks, so as to keep a holding pressure'against the under side of the platen.

In order to insure the rotation of the pasterollers, if found necessary, I have shown gearwheels C8, secured upon the ends of theirshafts and engaging with a toothed rack 10, formed upon the under side of the platen, so

' thatias the latter reciprocat-es it will cause the livered into the box, so that the roller is always kept clean. On the inner side of the box are other Scrapers 01 made to conform to the shape of the platen, and these, in conjunction with the scraper C9, serve to cleancff any paste which may be squeezed out, technically termed fat edges, thus keeping the rollers j clean at each movement.

The movement of the slide-platen is effected by the following mechanism: Upon the main driving-shaft B is a gear-wheel b2, Fig. 5, and this engages a similar gear-wheel b3, which has al crank or eccentric pin init, and this is connected by a rod b4 with a rocker-arm a3,.fixed upon the shaft a2, which is suitably journaled below the paste-box. From this shaft a2arms a4 extend upwardly upon each side of the paste-box. These arms have their upper ends vertically slotted, and a rod c, which is tixed transversely upon the top of the platen, has its ends extended so as to enter these slots. When the machine is in motion the arms a4 are caused to oscillate about their fulcrum shaft a2 by the connections above described, and the platen will thus be recip'rocated to pass inwardly over the paste-roller c3 and then move outwardly over the end of the paste-box, so as to meet the can-puller, which is so actuated as to move in the opposite direction from the platen, meeting it when it is projected from the paste-box and receding from it when it again returns over the paste-box. These reciprocating movements of the platen also rotate the paste-rollers alternately in opposite directions and keep them always fully supplied with paste, while the Scrapers previously described keep them clean and prevent any accumulation of paste upon them.

The can-puller consists of two side plates cl3, which are connected with the carriers upon the outside of the runway, as previously described. Between these plates the top pressure-roller G is journaled, the ends being mounted in the radially-sliding block g and pressed down by springs g', so that the roller will always exert a pressure upon the top of the can and at the same time yield to any inequalities in the surface upon which it bears. This pressure-roller insures a rolling motion of the can as it passes beneath it, and also smooths out all blisters and wrinkles upon rthe label when it is applied to the can, tnally pressing the lap down, so that the label will be smoothly and properly applied. The sliding boxes are mounted in adjustable bearings in the sides of the can-puller and are adjusted by means of screws when the primary position of the pressure-roller is being determined.

Upon the inner surface of the side plates D of the can-puller and forward ofthe pressure-roller is journaled the pullenroller H. In the present case I have shown a'single roller extending entirely across between the sides, instead of havingA two short rollers which only press upon the ends of the can, as in my former patent. This puller-roller thus bears` on the lap of the label as well as the TOC IIC

mafias pressure-roller above and makes it adhere with more certainty by reason of its being pressed down twice. This roller also prevents the end of the label from springing up when released from the locking-bars and keeps the label down to its place until it is fully applied to the can, thus insuring its going on straight. The locking-bars Q will be hereinafter more fully described. They are projected across the label-pile to hold the labels in place until the proper time, and when they are withdrawn the roller prevents the pile of labels beneath fromhspringing up and the topmost one from curling or otherwise becoming displaced. rlhe spindles of the puller-roller are journaled incarrier-blocks adjustable by screws h and movable radially toward the center of the can.

J are short stops on the can-puller, adapted to extend alittle over the can, and they are set by screws in the frame of the can-puller, so as to prevent the can from rushing ahead when pulled by the can-puller.

The paste-rollerK of the can-puller is journaled in segmental brackets k, which are pivoted at one end of the sides of the can-puller. At the opposite end they are slotted and have set-screws by which they may be adjusted,

so as to raise or lower the roller and cause it able material that will serve to distribute the paste properly. A corrugated metal roller serves very well, as these corrugations become filled with paste when passing under the slide-platen, and they in turn deliver it to the surfaces of thepaste-heads when passing beneath these.

The paste-heads being covered with rubber `have a tendency to take the paste from the metal surfaces, leaving the roller comparatively clean to return for a new supply from the slide-platen.

In my present apparatus, instead of raising `the canpulle'r by means o fdiagonal trackgrooves so that it passes above the can and is afterward dropped down to a lower level to engage the can, the can-puller moves in a single horizontal plane as it reciprocates, and the cans are delivered into the can-puller by a mechanismwhich I will now describe.A

The feed-chute L brings the cans to the apparatus and delivers them into the end of the runway, where they are allowed to roll upon a vertically-moving table N, and are arrested t and prevented from going beyond it by means of a forked stop M, having a transverselyextending part with a slot m, which is permanently bolted to the main frame of the machine. This slot allows of an adjustment for larger or smaller cans. The table N, upon which the cans are delivered from the feedchute, has a4 downwardly-projecting stem fn, movable in suitable guides, to insure a correct vertical motion. This stem is actuated by toggle-lever arms n', one of which is pivoted 'to a collar upon the stem n, and the other to some stationary part of the frame. By meansv of a connecting-rod or pitman o the central joint of the toggle-lever is connected with an oscillating lever O, fulcrumed to the main frame, having its upper end connected at p with a horizontally-moving slide P, so that when this slide -is reciprocated the table N will be alternately raised/ and depressed a short distance. `When in its lowest position a can is allowed to roll upon the table and is stopped against the upwardlyprojecting arms M. With the upward movement ofthe table the canis raised so as to be within the can-puller and in position to be moved along the runway. i Meanwhile the edge of the table which is presented toward the feed-chute L is raised high enough to form a stop and prevent any more cans advancing until the one already in the .can-puller has been carried back and the table again depressed, so as to allow another can to roll in upon it.

The slide P is moved as follows: A knob or projection cl3 in the carriers impinges against a pin p' upon the slide When the can-puller Amoves toward the paste-boxand thus reciprocates the slide and actuates the table, as previously described. The slide P has another pin p near the lever O, as shown in Fig. 1. Now when` the can-puller reaches the paste-receptacle its knob d3 will come in contact with the pin p: at that side and push it backward, causing the table N to beloweredwith a can on top, and on its'back travel, when arriving over the table again, will push the other piu p forward and thusraise the table Nandl bring the can rightunder the rollers of the can-puller. The table raises the 'can high enough to pass it over the top of the stop M. From the table the can will advance upon the can-ledges a5, which are slightly above the level of the table and have their ends, which are adjacent to the table, beveled orinclined, so that a can can be rol-led up these inclines upon the ledge. By reason oi4 the table being lower than these ledges there will be no pressure of the pressure-roller upon the top of the can while it is .on the table, but as soon as the can is advanced upon the ledges it will be raised to such a point that the pressure-roller` then acts upon the surface of the can after the latter has fully left the lifting-table. When the table is raised, it is prevented'from being accidentally lowered by reason of the togglelever joints passing slightly beyond the, centers, or a straight line of the levers, which acts as a lock and retains the table in its proper position until the can-puller reaches the end IIC) A ing over the label-pile these bars have a flat y 4 sia/lss 'of its travel. This also prevents the pressureroller from pressing upon the can while the latter is on the table.

As the tendency of metal moving over metal will be to slide, I have found it preferable to cover the can-ledges with rubber strips or any surface or substance to which the metal of the caps will adhere, so as to insure their rolling instead of sliding. The rubber also yields, so that the can is pressed slightly down into the rubber at all times and forms a frictional contact, which insures its rolling properly. This depression also compensates for the little difference in diameter caused by the thickness of the tin where the heads are put on to the body of the can and prevents the can advancing at a different rate of speed from the movement of the label, which would be the case if the larger diameter of the can ends should roll upon the ledges while the smaller diameter of the body of the can was picking up and placing the label upon itself.

The label-box I is situated beneath the runway and operates in a manner similar to that shown in my former patent. For convenience I have shown the box having one side hinged so as to turn outwardly to allow easy access to the inside of the box for the purpose of supplying it with labels. The box sides are also adjustable, forward or backward, by means of slots in the upper portion of the sides and corresponding projections, against v lit the different sizes of labels which may be used for cans of different sizes.

In order to form a stop for the label-pile, to hold them exactly in place and to relieve the top-most one, when necessary, I employ lugs v or holders, consisting of bars Q, extending into the runway from each side and projecting over the top of the label-pile X, as is well shown in Figs. 3 and 4. At the end projectpiece, which, when the bar is moved inwardly,

holds the label-pile slightly below the top of the label-box, or, more correctly speaking, below the can-ledge, which is a continuation ofv the label-box. By thus being held below the top of the box they are prevented from being There are four of these holders,

suitable guides at right angles to the move-y This slide engages the ment of the holders. p locking bars or holders by a pin or standard q2 with an antifriction-roller fastened on the Ahold the latter always against stud r.

These adholder and passing through the slide. This slide is designed to move the holders transversely, they being first raised in vertical planes by means of cam-surfaces 20, one of which is shown in Fig. 4. This slide is moved by a trigger-bar S, pivoted to the top of the frame and in the path of au operating-bar d4, shown in Figs. l, 2, and 5 as projecting below the lower part of the slotted carrier by which the can-puller is operated, and also by a post or pin r fastened to the cam against which the trigger impinges. The operating-bar d4 strikes the bar S von its outer inclined end and carries it along until d4 is beyond the inoline, and, consequently, releases it, pushing all the while the stud r on slide R ahead of it. A spring s on top of trigger-bar S serves to The extent of projection of operating-bar d4 toward the inclined end -of S causes a sooner or later release from the latter, and therefore determines the time and extent of time yto operate the bars Q. Vhen the operating-bar d4 returns, it will take ,hold of trigger-bar S on its side and simply carry it away from stud r and before it until it has passed, when trigger-bar S will spring back again against stud r by means of its spring s. The length yand position of this operating-bar of the carrier determine the time when the lock is opened and what length of time it is held open. A spring fr', carried yby the slide, returns the cam to its normal position and also returns the holders to their places to hold the label-pile. f

When the slide and the holder are in the position to hold the label-pile in the box, the holders are absolutely locked, cannot vbe opened by any upward pressure which may be exerted, and can only be vopened by the movement of the trigger-bars, as before described. The rising movement of these holding and locking bars is for the purpose of carrying them first to a plane sufficiently high to insure their return above the labels without danger of catching the edges of the pile.

When the can-puller and the carrier-piece move forward to receive a new can, the operating-bar of the carrier swings the triggers out of the way, and a springs returns it again against the post of the slide to `be in readiness to open the lock when it returns with a can.

If desired, the lower surfaces of the holders which impinge upon the label-pile may be surfaced with rubber, so that the labels -will be less liable to slip than if the surface' was metal.

The locking mechanism being carried by the frame, I am enabled readily to adjust it to various lengths of labels in a manner similar to that shown in my former patent.

The paste-heads T, by which the ends of the labels arel supplied with paste, are carried by dovetailed holders or seats t, (see Figs. 10 and l1), upon which they are adjustable and held when in proper position by set-screws. The dovetailed carrier or seat has an upwardlyextending stem or rod t', which is movable in suitable guidesto give it avertical reciproca' tion. Y These bearings are formed in an angleiron which is supported by the two shafts ff.

The guide-stems of the paste-heads have fastened upon them slot-pieces, also pieces forked at one end to overlap the part with the bearings of the stem, so aste prevent the stem from turning and to insure a true vertical movement. The slot-piece is for the purpose of attaching a pin a upon a lever U which enters the slot. The guidesterns are moved up and down alternately by the levers U, pivoted upon the angle-iron f2, as shown at u', One end of the lever Uhas a counterweight 'U'. `The other end has a pin u, which enters a slot 252, connected with the vertically moving stem. Upon the opposite side of the fulcrum U is another pin a2, which carries an antifriction-roller, and this enters a curved slot in the cam V. `This camis similarin appearance to a quadrant having converging sides extending from the curved portion of the cam and fulcrumed upon the shafts ff. A slotted-.opening is made in each at a point about midway between the fulcrum-shaftf or j and the curved slotted end V, and through this passes a bolt e', which connects the segmental cams with one of two oscillating arms E E', and these arms are connected by a rod e, so that the cams are caused to swing backward and forward, as these arms are moved by the action of the crank b. The slot into which the pin or bolt e enters allows ofja suitable adjustment, so that the movement of the parts can be regulated. This adjustment serves to regulate the bearing of the pastehead upon the label-pile.

In order to allow an independent adjustment of the paste-head with relation 'to the paste-roller, I cnt the stem t in two and tit a sleeve t3 over the two ends, and when set` to the proper length I hold the ends firm in the sleeve by means of set-screws. By this arrangement the stem can be lowered or raised and any adjustment with relation to the paste-roller can be made. (Shown in Fig. 8.)

The curved slot or groove V is formed with two different radii. One part of this groove is circular, having' its radius from the center upon which the device is fulcrumed-that is, the shaft f or f.V While the roller or pin .which projects from the lever into the slot lies in this part of the curve, there is no movement ot' the lever or the paste-heads, and the head thus remains at a height sufficient to allow the paste-roller K of the can-puller `to pass beneath it and apply the paste to it.

The remainder of the cam-slot then deviates from the curvature of the first portion, so that when Vthe pin from the lever U begins to travel in this portion of the slot it willlbe gradually raised and the end ot the lever which carries 4the paste-head guide-stem will be depressed,

same manner and alternately, so that one is first depressed upon one end of the label and the other one afterward, depressed upon the otherend.

The counterbalance-weights n', previously described, are sufcient to counterbalance the 'weight ot' the paste-heads and their guidestems and connections.

In order to prevent paste from being applied to any more than the uppermost label at the end which is first picked upby the can, either by displacement of the labels or by any paste `which may be squeezed out, `the paste-heads are so set that they will apply the paste a little distance away from the extreme end of the label, as shown' in my formerpatent, and when the end of the label is picked up it is drawnoutward by the act ofthe paste head letting go the label, so that it is distributed to the extreme end after the label has beenraised from the pile. f

In order. to prevent any accumulation. o paste which Vwill become squeezed lout and produce what is called a fatedge, I provide a device consisting of a plate W, which is secured in such a manner that when the pastehead rises from the label it passes with its edges invclose proximity to this plate, and the paste is `thus scraped oi and prevented from accumulating upon the paste-head, and when the paste-roller of the can-puller passes under the paste-.head it spreads out the paste which has just been scraped off, so that the pastehead always returnsf to the label with its edges scraped and clean, thus preventing any such undesirable accumulation vof paste. This device I find to be more necessary at the end of the label which is tirst picked up than at the opposite end, where it is of `a certain advantage to allow the end of the label to becorne well pasted, so as to insure a better lap. when the label is put around the can. y

The device W for scraping the paste-heads is secured by set-sere ws, so as to have any necessary adjustment to adapt it exactly to the parts with which it is to operate.
